Epoxy resin to seal it

deanrobi said..
guys, slight mishap today with a reef, damage to area adjacent to fin box where the fin has gone backwards and sliced a small (3cm) ding into the board, its a Starboard, not the brush carbon model,

What do i use to repair it? is is it the same as grabbing a ding repair kit from the local surf shop?

Yes.. Just make sur the ding repair kit is for epoxy (most are) and brushed carbon boards are the same a repairing a normal epoxy board..

If this video teaches me anything it's "Take it to a Pro" and pay the dough! Which is probably why the ding fixer posted it.

The video is nice, but there are many tricks to use to make it much simpler to do for the non-pro:

- use a precision scale (less than $20 on amazon) to weight the 2 epoxy components, it is much much easier to do than looking at volumes
- cover the outside of the ding with masking paper tape, the edges of the cloth going on top of it. once hard the tape will provide an easy visual guide; just sand till the tape is gone.
- prepare and wet the cloths on a carboard, taking away most of the resin without worrying about messing up the board. Just wrap the wetted cloth on the ding, no resin dropping out everywhere.
- cover the wet cloth to let hit harden: either with cooking paper + tape, or just directly PVC tape on it (we call it "poor man vacuum bagging"). once the resin is semi-hard pushing on the tape helps the resin stick with the ding, you can even "sculpt" the resin in shape, useful for rails...
- same for the final hot coat layer: put some resin then tape it: this way sanding is minimal and can be done by hand easily. (wet sanding by hand makes no dust, useful at home)
- once the resin is hard, one hour at 40C (no more) under a lamp or with a hot water bottle hardens it as much as one week at 20C, eases sanding. Do not heat too much (never never above 50C) not too early or the combination of the resin that fluidifies and the air pressure form the foam risk to creates holes by bubbles in your repair
